Can Rust Remover Be Sprayed on Brake Discs?

[OAdelyn]

Rust remover should not be sprayed on brake discs. Spraying rust remover on brake discs can corrode them, affect braking performance, and may even cause the brake discs to fail, leading to brake failure. Rust on brake discs is a normal phenomenon. Since brake discs are made of metal and are unprotected, they are directly exposed to the air and will oxidize and rust. While rust remover can prevent rust, the oil on the surface of the brake discs will reduce braking efficiency, causing a loss of friction between the brake pads and the brake discs, which can result in brake failure and endanger driving safety. The function of brakes is to reduce speed or bring the vehicle to a stop. Their working principle relies on the friction between the brake pads and the brake drums, as well as between the tires and the ground, converting the kinetic energy of the moving vehicle into heat energy through friction, thereby slowing down or stopping the vehicle. Brake discs do not need rust removal. Brake discs are made of HT-250 standard gray cast iron, and rusting in the air is an inevitable reaction. Additionally, since brake discs are fixed at the lowest position of the car, splashing rainwater or dirty water during driving will inevitably accelerate their oxidation reaction.
